Maintenance and Service

Procedures

Air Filter – Check

A dirty air filter will restrict air flow into the

carburetor, will cause poor fuel economy, and

may damage the engine. To keep the generator

in good operating condition, service the air filter

regularly. Service the air filter more often when

operating the generator in extremely dusty areas.

Note: Never operate the generator without the

air filter in place. Operating the generator without

the air filter in place will result in rapid engine

wear.

Remove the fan cover panel (5) by removing the

screws (6) and lifting out. Unscrew and remove

the air filter lock (1) and cover case (2). Remove

the clip (3) and air filter (4). Make sure both the

paper and foam elements of the air filter (4) are

clean and not damaged. If the foam element is

dirty, wash it. If the paper element is dirty, knock

the dirt off. If either element is damaged, replace

the air filter.

Use a nonflammable solvent or a mixture of

household detergent and warm water to wash

the foam element. Rinse the filter thoroughly to

remove all of the cleaning solution. Never let the

foam element contact engine oil.

Note: Do not wring out the filter. Wringing out the

filter may damage the filter.

Use a damp rag to wipe dirt from the case and

cover. Install the air filter into the housing. Place

the clip over the filter. Place the cover case over

the filter and clip. Reinstall the lock and screw in

the cover panel.

Battery – Test/Replace (If Required)

Shock/Electrocution Hazard: Do not

operate this

equipment or work on this equipment

unless you

have read and understand the

instructions and

warnings in the Owner’s Manual. Failure to

follow the

instructions or heed the warnings will

result in

serious injury or death.

Never disconnect any charging unit circuit or bat-

tery circuit cable from the battery when the char-

ging unit is operated. A spark can cause an

explosion from the flammable vapor mixture of

hydrogen and oxygen that is released from the

electrolyte through the battery outlets. Injury to

personnel can be the result.

Disconnect the negative battery cable from the

battery and secure it so that it will not contact the

battery. Disconnect the positive battery cable.

Use a Voltmeter or a multimeter set to VDC to

measure the battery. If the battery has less than

12.7 volts, charge the battery. If the battery has

less than 12.4 volts, replace the battery.

Remove bolts (2) and plate (1). Remove the

battery and dispose of properly.

Set the new battery into position. Install plate (1)

and bolts (2). Connect the positive battery cable.

Connect the negative battery cable.
